1/3 of 81 = 81 • 1/3 = 81/3 = 27
Answer:
The unknown is 100
Step-by-step explanation:
A straight line is 180 degrees
We have two angles x, and 80
x+80 = 180
x = 180-80
x= 100
The answer is -30-25 which in turn becomes -55
Step-by-step explanation:
9 = a7 + b
-2 = a9 + b
b = 9-7a and b = - 2-9a
9 - 7a = - 2-9a
2a = - 11
a = - 5.5
b = 9 - 5.5*7 = - 29.5
y = -5.5x - 29.5
Answer:
7 and -6
Step-by-step explanation:
7 + (-6) = 1
7 * (-6) = -42
